WATER HOSE
2. Repeat steps until water runs clean.
3. Inspect the cones and venturi tube to make

4. Shake the heater vigorously to clear water off
of the combustion cones to allow proper igni-
tion of gas at the inner cone.
5. Return the heater to its original hanging
position.
6. Relight the heater to dry out the cones and the
venturi tube.
C. FILTER
A. During continued use:
- Remove fi lter and shake off dust.
- Do not squeeze or tap fi lter while fi lter is in-
stalled on heater. Doing so will cause dust to be
blown into venturi tube or combustion cones.
B. After continued use or before building
repopulation:
- Remove fi lter and shake off dust.
- Use compressed air or water (standard faucet
pressure) to clean it.
- Do not use high pressure water, air, or a wash-
ing machine. Filter material damage may occur.
- If water is used, squeeze out excess water from
fi lter before installation.
